Changes to the Canadian Electrical Code
Many updates have been addressed in the 21st edition of the code. A new section was added to cover requirements for passenger ropeways. In addition, there are significant changes to reflect new technology and industry practices.
This Code covers all electrical work and electrical equipment operating or intended to operate at all voltages in electrical installations for buildings, structures, and premises, including factory-built relocatable and non-relocatable structures, and self-propelled marine vessels stationary for periods exceeding five months and connected to a shore supply of electricity continuously or from time to time, with the following exceptions:
a) installations or equipment employed by an electric, communication, or community antenna distribution system utility in the exercise of its function as a utility, as recognized by the regulatory authority having jurisdiction, and located outdoors or in buildings or sections of buildings used for that purpose;
b) equipment and facilities that are used in the operation of an electric railway and are supplied exclusively from circuits that supply the motive power;
c) installations or equipment used for railway signalling and railway communication purposes, and located outdoors or in buildings or sections of buildings used exclusively for such installations;
d) aircraft; and
e) electrical systems in ships that are regulated under Transport Canada.
